I am designing a process that interacts with external customers as well as internal users. I have an external web server that will be accessing the process from the K2 server. What ports and what protocols must be allowed throught the dmz firewall for the web server to be able to request and receive response form the K2 server in a default install.

I believe I need 5252 but what is the protocol over that port? Are there any others?

That would be for the workflow functionality.  If you are using SmartObject calls as well, you will also need port 5555 access.


Protocol should be TCP.


 i.e. Web server *ANY* <--> K2 Server 5252 and 5555 TCP


If you are using the MOSS Web workflow, you will also need to allow SQL Access from the MOSS WFE to the SQL K2 Web workflow database.
